PoE High Temperature Switch
Hardened PoE switches are designed to withstand harsh environments, including excessive vibrations, shocks, and high levels of electromagnetic interference. Not cheap though as you may imagine. They are designed for industrial use, but they are available. Item #: EVNSL0272BL-0001 CAT6 250-MHz Stranded Ethernet Patch Cable with Slim Form-Factor Molded Boot - Shielded (S/FTP), CM PVC (RJ45 M/M), Blue, 1-ft. 3-m) Provides four Fast. In addition to transmitting network data, a PoE Switch has a built-in Power over Ethernet injector to supply up to 100W Power over Ethernet (PoE) to standards-based 802. 3bt compliant devices such as IP cameras, VoIP phones, and wireless access points. When connecting network. In my attic are 2 network cables running to my 24 port Ubiquiti PoE switch. One is running a WAP the other is doing nothing right now. [pdf]
Huawei Core Switch Layer 3 6700
The S6700 series Ethernet switches are next-generation 10G fixed switches. It can function as a core switch. Huawei S6700-24-EI, supporting 24 GE SFP/10GE SFP+ ports, is one of the Huawei S6700 series switches. This series delivers high-performance, super-reliable 10 GE switches with comprehensive Quality of Service and security capabilities. The S6700 is ideal for use as access switches in large-scale. Do you have a question about the S6700 Series and is the answer not in the manual?

Control the access to the switch ports
To block unauthorized access to switch ports, switches support a feature called port security. This feature allows you to configure which devices are allowed or blocked on each port. A VLAN is a switched network that is logically segmented by function, project team, or application, without regard to the physical locations of the users. In today's topic we will learn about switch port mode access and how its configuration is done on Cisco switches. This can be a security risk when users connect. In the following we explain the four methods (port-based, single, multi, and MAC-based) and we illustrate the usage scenarios for each one. [pdf]FAQs about Control the access to the switch ports

Aggregation of two fiber optic cables on a switch
Fiber aggregation is the act of combining many fiber optic cables into one high-capacity network connection. Fibers in these points are either spliced. With AXIS D8308 Fiber Aggregation Switch you can connect multiple Axis devices using fiber midspans over long distances. By design, it therefore provides resiliency because it will always be deployed in pairs of switches and comes with a recommendation to deploy only dual hot swappable power supplies and redundant fans in each switch to. In computer networking, link aggregation is the combining (aggregating) of multiple network connections in parallel by any of several methods. Link aggregation increases total bandwidth beyond what a single connection could sustain, and provides redundancy where all but one of the physical links. [pdf]
